I started coming here with friends to play Racquetball. Their courts are well-lit and I usually don't have to wait for one. Overall, the Racquetball courts are maintained fairly well with maybe the exception of court 4 (there is a divot in the floor that is about as big around as a baseball and about a quarter inch deep in the serve box).
I'm not sure how well maintained the tennis courts are, but it seems like they pay a lot of attention to them.
The rest of the park is really nice. The baseball fields look awesome and the basketball courts look good. Overall it's a fairly peaceful place and there is no shortage of things to do. Great park!
